Ten years after graduating Austin has found himself awaiting some important news the week before the reunion. Still single and living with Kevin, his best friend and professional jerk, Austin enlist his younger brother, Cody, to document the week leading up to the big day. Along with their compadre Gordon, the three look to have a good time reminiscing until an old crush returns. Brooke Hannigan is also back and reignites the schoolboy crush Austin had a decade ago, but Brooke and Gordon are a little too friendly for Austin's liking. That, along with some very bad news, sends Austin into a debilitating depression that only his friends can get him out of in time for the reunion.
